Answer:
x = 59
Step-by-step explanation:
Since the angles of a quadrilateral add up to 360°, simply set the sum of all the angles to 360°:
x + x + (2x + 3) + (2x + 3) = 360
Combine like terms:
2x + 4x + 6 = 360
6x + 6 = 360
Get the x's on one side:
6x = 360 - 6
6x = 354
Solve by dividing by 6:
x = 59
